Odour free toilet system

ABSTRACT

An odour free toilet system comprises a vent head having an inlet which is magnetically attached to a toilet bowl. The inlet is positioned under a toilet seat and a toilet lid in between a pair of mounting assemblies for mounting the toilet seat and the toilet lid. The vent head is positioned behind the toilet seat and the toilet lid. The vent head having the inlet is out of the way of the toilet seat and the toilet lid in any position of the toilet seat and the toilet lid. The odour free toilet system further comprises an outlet fitting in the rear part of the top surface of the toilet bowl with the vent head covering the outlet fitting. A suction fan and plumbing provides air suction to the outlet fitting thereby providing air suction to the inlet close to the source of toilet odours.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions describe the preferred embodiments of theinvention by way of example only.

FIG. 1 shows an exploded view of an odour free toilet system 100. Atoilet bowl 102 has a top surface defining a pair of mounting holes 122a, 122 b for mounting a toilet seat 124 a and a toilet lid 124 b. Aplate 106 made of a ferromagnetic material such as iron, nickel andcobalt, is adhesively secured to the top surface of the toilet bowl 102in between the pair of mounting holes 122 a, 122 b. A vent head 104having an inlet 108 further comprising at least one magnet ismagnetically attached to the plate 106 as will be further explained inthe hereinafter. The top surface of toilet bowl 102 further defines anoutlet hole 110 for receiving an outlet fitting 112. An outlet hose 114has on one end an outlet hose fitting 114 a and on the other end anoutlet hose fitting 114 b. The outlet hose fitting 114 a matches theoutlet fitting 112 at the bottom end thereof, thereby securing theoutlet fitting 112 in the outlet hole 110. The outlet hose fitting 114 bmatches a fitting 118 of a pipe 116 connected to a suction fan 120 suchas a common TT 100 vent having an input rating of about 187 cubic meterper hour (about 110 cubic feet per minute) mounted in a bathroomceiling. The fitting 118 can be a wall fitting, the pipe 116 can beconcealed partly in the bathroom wall and partly in the bathroom wallceiling. The vent head 104 covers the outlet fitting 112 so that inlet108 provides air suction to the toilet bowl 102 for disposal of toiletodours out of a roof vent (not shown).

Advantageously, air suction is provided close to the source of toiletodours.

Preferably, the vent head 104 having the inlet 108 forms a substantiallysymmetrical T-shape so that the outlet hole 110 and the outlet fitting112 can be placed on either side of the toilet bowl 102.

Preferably, the plate 106 has a thickness ranging from about 1/16 of aninch (1.5 mm) to about ⅛ of an inch (3 mm).

FIG. 2 shows a top view of the vent head 104 having the inlet 108.

Preferably, the vent head 104 having the inlet 108 is made of apolymeric material.

The vent head 104 has a width Wh, a depth Dh, and a height Hh. The inlet108 has a width Wi, a depth Di, and a height Hi.

Preferably, the vent head 104 has the width Wh of about 190 mm (7.5inches), the depth Dh of about 39 mm (1.5 inches) and the height Hh ofabout 18 mm (0.7 inches).

Preferably, the inlet 108 has the width Wi of about 86 mm (3.4 inches),the depth Di of about 72 mm (2.8 inches), and the height Hi of about 9mm (0.35 inches).

FIG. 3 shows a bottom view of the vent head 104 having the inlet 108. Atleast one magnet is required to attach the vent head 104 having theinlet 108 to the plate 106. Shown are three magnets 302 a, 302 b, 302 csecured to the vent head 104 having the inlet 108.

Advantageously, the vent head 104 having the inlet 108 can be manuallyremoved without tools for cleaning purposes.

Preferably, the vent head 104 having the inlet 108 further comprises abottom gasket 304 for sealingly engaging the bottom of the vent head 104having the inlet 108 to the top surface in the rear of the toilet bowl102 when the vent head 104 having the inlet 108 is magnetically attachedto the plate 106.

Preferably the bottom gasket 304 is made of a soft polymeric material.

FIG. 4 shows the toilet bowl 102 with both toilet seat 124 a and toiletlid 124 b in an up position. The inlet 108 fits under the toilet seat124 a and the toilet lid 124 b between the mounting assemblies 402 a,402 b of the toilet seat 124 a and the toilet lid 124 b. The vent head104 is hidden from view behind the toilet seat 124 a and the toilet lid124 b. The inlet 108 is set back a predetermined distance D from the rim404 of the toilet bowl 102.

Preferably, the predetermined distance D ranges from about 15 mm (0.6inches to about 25 mm (1 inch).

FIG. 5 shows the toilet bowl 102 with both toilet seat 124 a and toiletlid 124 b in a down position. The vent head 104 is rearwardly of thetoilet seat 124 a and the toilet lid 124 b. The inlet 108 is hidden fromview under the toilet seat 124 a and the toilet lid 124 b.

FIG. 6 shows the toilet bowl 102 with the toilet seat 124 a in a downposition and the toilet lid 124 b in an up position. Both the vent head104 and the inlet 108 are hidden from view, the toilet seat 124 a in thedown position hides the inlet 108 from view and the toilet lid 124 b inthe up position hides the vent head 104 from view.

The vent head 104 having the inlet 108 is out of the way of the toiletseat 124 a and the toilet lid 124 b in any position of the toilet seat124 a and the toilet lid 124 b.

Advantageously, the vent head 104 having the inlet 108 are unobtrusivein actual use, hidden from view in most positions of the toilet seat 124a and the toilet lid 124 b.

Preferably, the outlet fitting 112, the outlet hose 114, the outlet hosefittings 114 a, 114 b, the pipe 116, the fitting 118, and the side inlet706 are 1 inch (25.4 mm) plumbing parts.

Advantageously, the odour free toilet system 100 allows for anyhazardous electrical items to be placed remotely from a user of theodour free toilet system 100.
